NAEMD is the Best Event Management Institute because I have done PG Diploma in Event Management in the year 2015-16 from NAEMD, Jaipur, and got many practical training in various events and exhibitions and now I am doing own business in the same field, but still I think you don't need to graduate from these institutes to enter in the event industry because you will not learn anything extra from these institutes. Because event management is a practical learning not a theoretical. So if you have any contact in this industry to enter then go ahead dong go for any course then.
